A vehicle seat configured in such a manner that vibration occurring in the seat body can be suppressed without adding a special device such as a dynamic damper. A vehicle seat is configured in such a manner that an upper rail (26) connected to the seat body is slidably supported by a lower rail (28), which is affixed to the vehicle body side, through a pair of slide guides (42, 44) disposed next to each other in the front-rear direction of the seat. The distance (L) between the slide guides (42, 44) is set to be less than the half of the maximum slide amount (S) of the upper rail (26) relative to the lower rail (28). As a result of the configuration, the rigidity of support of the seat body by the vehicle body is reduced to reduce the resonance frequency of the seat body in the front-rear direction. This enables the resonance frequency of the seat body in the front-rear direction to be shifted from the resonance frequency of the vehicle body when the engine of the vehicle is idling.
